About

I am an Engineering and Tooling professional with progressive experience in Tool Room leadership, injection molding, and manufacturing engineering across local and global operations. Currently, I lead Tool Room operations as an Engineering Manager focused on mold reliability, precision support, and continuous improvement. Previously, I managed regional tooling across Mexico and Malaysia, drove NPI programs for medical injection molds, and began my career as a Tooling Engineer in tool design and machining support (CNC/EDM).
